Furutec Electrical started to manufacture busduct system in Penang, Malaysia since 1995 under the license from Furukawa Electric, Japan. In 2008, EITA Resources Berhad ventured into designing and manufacturing busduct system and Furutec became a wholly-owned subsidiary of EITA Resources Berhad which is a public listed company in Malaysia.

Having benefitted from more than a decade-long of technical collaboration with Furukawa, Furutec is noted for its relentless and uncompromising commitment on quality and excellence as the Japanese manufacturing practice and culture have been firmly embedded into Furutec busduct system. Today, Furutec has more than 19 years of experience in the manufacturing of busduct system that meets international standards. This product is of the finest quality and reliability, utilising the stringent Japanese know-how and technology.

Our well-equipped R&D facilities have enabled us to continue to research and verify our product in accordance to the various requirements under IEC 60439-2 (old) and IEC 61439-6 (new) as well as the fire resistance aspect of the product.

Besides Furutec’s in-house R&D activities, we also look outwards to find new opportunities and complement our in-house capabilities. We tap into local scientific expertise and gain useful insights for future growth through technical collaborations with public universities. To better capitalize on the home grown knowledge, Furutec Electrical has entered into a technical collaboration agreement with local university to jointly research and investigate the development of new raw materials used in the manufacturing of busduct system.

With the merit from this R&D effort, our full product range of copper HP-ES busduct (from 400A to 6300A) is eventually able to be successfully type-tested and certified by a reputable independent testing authority, KEMA/DEKRA in compliance to IEC 61439-6. Additionally, our tap-off unit is also type tested and certified to IEC 61439-6 for temperature rise test, short circuit test and thermal cycling test.

The compact sandwich design of Furutec busduct can be configured to 3-phase 3-wire (3P3W), 3-phase 4-wire (3P4W) or 3-phase 5-wire (3P5W with integral earth bar).

Due to the existence of non-linear loads in today’s modern buildings, high harmonic neutral current overheats the neutralconductor and deteriorate the performance and life span of equipment. 200% neutral bar is offered to handle the overheating and increased neutral current caused by the harmonic effect.

Copper and aluminium conductor are of the conductivity 99.98% and 60% respectively. It meets all electrical, thermal and mechanical properties and comply to the relevant international standards, such as JIS H3140, ASTM B187M, BS EN 13601, etc.

Each copper and aluminium conductor (except at joint parts) is insulated with polyester films (-70oC to +150oC). The rated insulation voltage is up to 1000V at 50Hz or 60Hz of frequency. Each conductor is tin-plated to provide protection from corrosion and high conductivity.

Furutec busduct system is of the low impedance type and totally enclosed for protection against mechanical damage and dust accumulation. The busduct housing is made of Electro-Galvanized sheet steel with epoxy powder coating.

Conductors are fully enclosed with the busduct housing, which provides an excellent heat dissipation, thus improving the power transmission efficiency and reducing voltage drop. The construction of busduct housing is compact and robust in design to meet the rated short-circuit ratings.

Furutec busduct joint features a maintenance free double-bolt joint design. This double-bolt joint system ensures a sufficient electrical contact area and good mechanical strength. Its high tensile clamping bolts in duct-to-duct jointing do not penetrate through the conductors. A spring steel material named as leaf spring that is wider than the conductors, is used to ensurea sufficient pressure on conductor contact area. This clamped joint having benefitted from a decade-long Japanese Technologygenerates less heat at busduct joint as compared to bolted joint system, which necessitate the drilling or punching of holes through the conductors with the bolt holes causing distortion to the lines of current flow. This clamped joint with leaf springs also has a more even contact pressure than the one using bolt-through joint.

Note:Weather Shield is providedfor outdoor installation.



Method of Mounting

Degree of Protection

For horizontal busduct installation, the edgewise / flatwise hanger or flat hanging clamp shall be installed in every 1500mm interval.

Vertical busduct system shall be supported adequately with vertical spring hanger / vertical hanger on each floor. Intermediate supports shall be provided if floor height exceeds 5000mm.

Furutec busduct housing is designed and constructed to meet the requirement of indoor and outdoor installation. The degreeof protection of Furutec busduct housing is verified and tested to meet the requirement of IP42, IP65 and IP66 in accordance to IEC 60529 by independent testing authority.

Reducer is used to reduce busbar sizes to the final load. It provides users with more economic power transmission anddistribution method. The minimum length (L) is 600mm and the reduction from a higher busduct rating to a lower busduct rating should not exceed 45%.




Remark: If the reduction is more than 45%, a protective device (e.g. circuit breaker) must be installed in between both busduct feeders.

The busduct system expands and contracts when the electrical load and the ambient temperature vary. The expansion unit is the transition section compensating the thermal expansion and contraction. The requirement of expansion unit in a vertical installation is determined by the method of how both ends of busduct system are supported. The use of plug in hole and total length of vertical busduct are important factors of determining the requirement of expansion unit.

31 | INSTALLATION & MAINTENANCE PROCEDURE

INSTALLATION & MAINTENANCE PROCEDURE

When the busduct arrives at project site, check the type and quantity of busduct feeders and accessories from delivery order. Inspect for physical damages caused during transportation and unloading.

Keep the busduct in a dry place, away from water and moisture, preferably under a roof protected from rain. Cover the busduct with water-proof material if necessary.

Do not lay the busduct directly onto the ground or in an upright position. Always place pieces of wood under the busduct and stack up firmly.

For long periods of storage, ensure that the busduct is placed in a dry place free from condensation.

To prevent the busduct joint from being soiled, wrap both busduct ends with water-proof material while unpacking. Before busduct joint installation, examine the conductor contact surface or insulation materials for any damages. It is important to ensure that the joint sections are not soiled with dust, dirt and other foreign matter.

Sufficiently strong materials and equipment must be used during handling and lifting to reduce the risk of personal injury and equipment damage at site. Busduct must be handled with care to avoid damage to internal components and metal housing.

During unloading, do not drop it or let it hit with other objects. Do not drag busduct across the floor or across other busduct sections. A fork lift may provide a more convenient method of handling and has the added advantage of permitting it to be lifted between levels.

Platform/Scissor lifts or elevators, either manually or power operated, can be used advantageously in moving the busduct between elevations. Remember to check that the total weight of personnel plus busduct is within the capacity of the lift/ elevator.

If a crane is used to move the busduct, use nylon straps and distribute the weight on each lift. If rope is used, insert thick pieces of rag, foam or corrugated cardboard between them to prevent the busduct from being damaged/scratched. Do not place slings, rope or chains around the busduct ends since damage can easily occur. For busduct rated 2500A and above, pieces of strong wood should be used when rope is applied, in order to prevent the busduct housing from being deformed.

If a fork lift or similar hoist is used, properly position the busduct on the fork to distribute its weight. Careful approach is a must to avoid any damage to the metal housing that would break the phase isolators (ISP) at busduct joint.

While installing vertical busduct, it may be easier to lower the busduct feeder from one floor above where it will be installed. The busduct feeders are usually stored on the floor above their final location to facilitate lowering them into position. Protect both busduct ends when rising from horizontal to vertical positions.

When the installation work is suspended or halted at job site, the end section of the connecting busduct feeders should be protected against water and dust by covering them with polythene or other appropriate materials.

Determine the male and female sides of the busduct feeders to be connected.

Align the busduct feeders endto end.

Align the leaf springs so that the high tensile bolts can be fitted through the busduct housing.

4 5

Tighten the two bolts alternately to ensure even distribution of force is applied to the busduct joint. Tighten them until the leaf springs become almost flat and until the snap-pin-hole on the high tensile bolt is visible.

6

Cover the busduct joint section with joint covers on both sides. The installation is complete.

Insert the snap pins into the pin holes.

Busduct Joint

During Busduct Installation

In vertical busduct installation, busduct feeder which will be supported by vertical hanger should be installed before other busduct feeders in order to prevent a downward weight or load from concentrating on the busduct at the lower floor.

Flange end box must not be fixed permanently to the wall and floor. However, flange end box can only be permanently secured provided that all the busduct installations are completed (if unavoidable).

Vertical hanger/vertical spring hanger must be installed to the busduct system to allow for busduct elongation/expansion & contraction as well as the shrinkage of the building.

Waterproof curb is recommended to be installed at each floor opening where the busduct passes through. It prevents water (caused by plumbing leaks, fire sprinker system leaks, fluid spills, etc) from seeping into the busduct system. Additionally, the floor opening should be sealed with fire stop material to prevent fire from passing through the floors in case of fire in the building.

Connection with Equipment



1. After the completion of busduct installation at project site, it is advisable to carry out a thorough inspection of the whole busduct route, followed by measurement of insulation resistance / Megger.

2. Before conducting the measurement of insulation resistance, all the equipment connected to busduct system should be disconnected and MCCB rotary handle of tap-off units should be in ‘OFF’ position.

3. The insulation resistance value cannot be specified due to different length of the busduct and environmental condition. But if it is installed in a dry atmosphere, the value of resistance should be approximately 100 MΩ (500V Megger).

4. The following inspection procedures should be carried out. Determine whether:-

4.1) The busduct feeders are physically damaged.

4.2) All the connecting parts are fixed precisely (e.g. flange end box, tap-off units, etc).

4.3) The bolts for connecting the equipment are securely fastened.

4.4) The busduct joint are tightened in accordance to Furutec‘s requirement and recommendation.
